A free thinker is someone who does not let themselves be limited in their thinking by tradition, custom or standard practice. Independ-ent-minded at all times, a free thinker is not bound by any particular ideolo-gy. As a result, they can explore new avenues and develop innovative ap-proaches to finding solutions.

As a free thinker, VITA Zahnfabrik has al-ready proven its worth twice this year in the area of CAD/CAM restoration materi-als. The introduction of the hybrid ceram-

ic VITA ENAMIC at the start of 2013 was a real coup. However, that was just the beginning, and was quickly followed by the next highlight – the presentation of a new generation of glass ceramics in the shape of VITA SUPRINITY, a zirconia-rein-forced lithium silicate (ZLS) ceramic.

The considerable interest shown at the IDS press conference and at the VITA trade show booth clearly indicated one thing: the market is ready for a new gen-eration of glass ceramics!

Conventional lithium disilicate cannot meet increasing user expectations to the same extent as VITA SUPRINITY. The new generation of glass ceramics now meets the need for improved mechanical properties such as greater dynamic load capacity combined with improved usabili-ty thanks to optimized processing charac-teristics coupled with superb esthetic potential.

What are the possibilities afforded by VITA SUPRINITY? This issue of VITA INFO provides detailed information – so let your imagination take flight!

In addition to other fascinating topics, you will find exclusive background informa-tion, user opinions, case documentation and a whole lot more besides about zirco-nia-reinforced lithium silicate ceramic.

THE PERFECT COMBINATION

VITA SUPRINITY is not just the cornerstone of a new generation of glass ceramics; its development has also established a comprehen-sive system of tailored components (Fig. 1).

contact points that are gentle on the ma-terial, reducing the risk of the formation of microscopic cracks. Removal can be easily controlled with minimal tool wear.

Plaque-resistant surfaces with a brilliant shine can be achieved. The clinical instru-ments can also be sterilized.

StainsWith the 19 fluorescent VITA AKZENT Plus stains, you can stain and glaze VITA SUPRINITY restorations easily and effec-tively, both internally during layering and on the surface. You can choose between powder and ready-to-use pastes; BODY STAINS, GLAZE and GLAZE LT are also available as a spray.

These stains can be used to characterize any dental ceramic material, in addition to VITA SUPRINITY.

Veneering ceramicsThe low-melting, fine-structure feldspar ceramic VITA VM 11 was developed spe-cifically with the individualization of ZLS in mind (Fig. 3).

The precisely adapted CTE values of the framework and veneering material en-sure outstanding adhesion and reliable results with veneers that are not subject to warping or stress.

VITA VM 11 features a high level of trans-lucency as well as warm shade reproduc-tion and offers outstanding strength, min-imum shrinkage and high edge stability. Thanks to the excellent surface wettabili-ty of VITA SUPRINITY, layering can be applied directly without liner or wash-bake firing.

VITA VM 11 also offers superb firing char-acteristics and remains dimensionally stable even after it has been fired several times. With the proven VITA VM fine structure, a smooth, densely compact surface is achieved that can be easily milled and quickly polished.

ConclusionProduct solutions for polishing, character-ization and veneering that are adapted to the new generation of glass ceramics are the ideal complement to VITA SUPRINITY – providing practices and laboratories with outstanding results from a single supplier.

Material blanksVITA SUPRINITY is a pre-crystallized zir-conia-reinforced lithium silicate (ZLS) that reaches full strength after crystalli-zation firing. The material is suitable for anterior and posterior crowns, and can also be used on implants as well as for veneers, inlays, onlays and partial crowns. The material blocks are availa-ble in geometry size LS14 (18 x 14 x 12 mm). The shade range includes 0M1, A1, A2, A3, A3.5, B2, C2 and D2, each of which is available in T = Translucent and HT = Highly Translucent.

Polishing setsThe VITA SUPRINITY Polishing Sets (clini-cal/technical) facilitate efficient, reliable and cost-effective surface processing (Fig. 2).

The precise concentricity of the polishing instruments, matching grit sizes and the individual geometries enable polishing of occlusal surfaces, cusps, fissures and

In this interview, Prof. Gerwin Arnet-zl from Graz, Austria (Fig. 1) and Jens Richter, a dental technician from Roch-litz, Germany (Fig. 2) report on their ex-perience with the CAD/CAM restoration material VITA SUPRINITY.

Prof. Arnetzl, Mr. Richter, what do you personally consider special about the zirconia-reinforced lithium silicate ceramic VITA SUPRINITY, and what made you decide to use this glass ceramic in your own work?

Prof. Gerwin Arnetzl: Its composition comprising a high proportion of zirconia is what is unique, and, as a result, its mate-rial properties. In terms of the physical and mechanical characteristics such as flexural strength and load capacity, val-ues superior to conventional glass ceram-ics were determined during laboratory testing.

Jens Richter, dental technician: Also of benefit to the dental technician and den-tal surgeon is the fact that VITA SUPRIN-

ITY is transparent prior to firing (Fig. 3). As a result, direct visual verification of the thickness of the wall can be conduct-ed while performing milling on the model. And the dentist can immediately see the fit on the tooth stump. My tip: using red occlusion paper rather than blue is easier to distinguish!

In your opinion, what are the differ-ences compared to conventional glass dental ceramics?

Prof. Gerwin Arnetzl: One of the charac-teristic properties of VITA SUPRINITY is excellent edge stability. This is more con-ducive to allowing in-vivo try-ins to be performed in the pre-crystallized state – proceeding with caution, is, however, nevertheless required. Very simple occlu-sal corrections can be carried out if nec-essary as the material is particularly easy to process at this point.

Jens Richter, dental technician: In this class of materials, VITA SUPRINITY of-fers excellent edge stability and is easier to polish than lithium disilicate. A sin-gle-phase crystallization process is also implemented that can be performed using any dental vacuum furnace that offers

slow cooling. Furthermore, no particular firing trays or firing pins are required, al-though the manufacturer does recom-mend platinum pins and honeycomb firing trays. Firing paste is then no longer re-quired at all. The fact that edges and notches do not require stabilization is particularly beneficial in the case of inlays.

What are your expectations: how much reliability can the new zirco-nia-reinforced lithium silicate ceram-ic material VITA SUPRINITY provide in terms of a long-lasting, reliable clinical outcome?

Prof. Gerwin Arnetzl: Thanks to the supe-rior stability of the new glass ceramic in terms of optical characteristics such as natural translucence, fluorescence and opalescence, an esthetic alternative to zirconia is now available for the fabrica-tion of abutment crowns and implant crowns (Fig. 4).

Jens Richter, dental technician: Based on the initial studies and acknowledged me-chanical properties of the material, I am anticipating excellent long-term clinical results.

What are the benefits of VITA SUPRINITY?

Prof. Gerwin Arnetzl: Thanks to the good edge stability, precise final results are achieved. The firing stability also improves process reliability. Thanks to the tailored veneering ceramic VITA VM 11, the highest demands in terms of esthetics can be met.

Jens Richter, dental technician: The num-ber of steps required in total is also re-duced to a minimum, and the material of-fers superior shade effects.

Did you notice any particular aspects of interest during use?

Prof. Gerwin Arnetzl: When I saw the VITA SUPRINTY blocks for the first time, I was surprised by their crystal-clear struc-ture. During clinical use it then became apparent that during try-in in the patient‘s mouth, for example, the existing tooth and restoration structures were more clearly distinguishable as a result.

Jens Richter, dental technician: Despite the comparatively high proportion of zir-conia, the material features a superb cha-meleon effect. Moreover, the material also offers an appearance that is so natu-ral, only minor details – at most – require layering using the cut-back technique. I also consider the veneering ceramic VITA VM 11 to be a great success.

How would you judge VITA SUPRINI-TY in terms of its processing charac-teristics?

Prof. Gerwin Arnetzl: The ceramic offers a very homogeneous structure, which provides the basis for precise and simple processing despite the comparatively high strength. High-gloss polishing can

also be completed in just a few steps, us-ing either the VITA SUPRINITY Polishing Set, for example, or using standard in-struments (Fig. 5).

Jens Richter, dental technician: Be it pol-ishing, glazing or layering – work can be completed extremely efficiently either way. I am not a fan of just polishing when working with this class of materials, how-ever, it is easy to quickly achieve results of above average quality. The elimination of liner or washbake firing during the cut-back technique also saves time and money.

How does VITA SUPRINITY simplify processing in practices and labo- ratories?

Prof. Gerwin Arnetzl: Dental CAD/CAM technology with its standardized and au-tomated steps in itself makes fabricating all-ceramic restorations easier. VITA SU-PRINITY, on the other hand, was geared towards computer-aided machine-based processing using the subtractive milling technique right from the very beginning, and is thus perfectly tailored to suit the CEREC/inLab system.

Jens Richter, dental technician: The glass ceramic rounds off the range of VITA ma-terials for use with CAD/CAM technology perfectly, offering the user real added value.

Fig. 4: VITA SUPRINITY restorations are impressive thanks to natural esthetics.

What are the benefits here in your view in comparison with convention-al glass ceramics such as lithium dis-ilicate, for example?

Prof. Gerwin Arnetzl: In my opinion, the key benefits of VITA SUPRINITY lie in its physical and mechanical characteristics. Accordingly, the new material offers greater flexural strength, for example, as demonstrated in laboratory tests.

Jens Richter, dental technician: Process-ing is easy in many ways. It is clear that the development of glass ceramics has reached a new milestone.

AN INTERNATIONAL INNOVATION: ZIRCO-NIA-REINFORCED LITHIUM SILICATE CERAMIC

The Swiss esthetics specialist and dental technician Xavier Zahno (Fig. 1) is one of the first dental tech-nicians in the world to have worked with the new VITA SUPRINITY glass ceramic.

Here he presents the zirconia-reinforced lithium silicate ceramic – ZLS for short – using a patient case.

Initial situationThe patient is a man in his early forties. He is troubled by the large number of fillings in the visible anterior area (Fig. 2).

These are fit for purpose from the per-spective of an expert in dental medi-cine, however, they do compromise the visual appearance. The patient would like improved esthetics as well as a lighter tooth shade.

PlanningFrom the perspective of a dental techni-cian, restoration of the upper and lower anterior area would be preferable.

The patient chose to begin with up-per-jaw restoration. Accordingly, the decision was taken to restore regions 13 to 23 using veneers.

VITA SUPRINITY was selected as the restoration material. The ceramic scores highly thanks to natural translucency, fluorescence and opalescence, a combi-nation that comparable products cannot offer in this form.

Moreover, with VITA VM 11, a special veneering ceramic is available that is adapted specifically to VITA SUPRINI-TY, which also offers high translucency as well as very warm shade reproduc-

tion. In terms of production costs and the duration of production, it is an ad-vantage in this respect that a minimum amount of individualization following completion of cut-back is sufficient in order to achieve esthetic results with a vivid play of colors.

ImplementationThe attending dental surgeon creates conventional impressions. In the labora-tory, models are created upon which the veneers are to be waxed up.

For the model, a laboratory scanner was used to first take a double scan of the models with, then without, a wax-up (Fig. 3 to 6). The veneers were milled from VITA SUPRINITY blocks in shade A1 and translucency HT (= highly trans-lucent), see Fig. 7 and 8.

At this stage in processing, the material is still in its pre-crystallized, semi-trans-parent state.

Cut-back can generally be carried out prior to crystallization firing. In this case, however, final crystallization was completed first as a basis for discussion with the patient, and try-in carried out of the fully anatomical veneers (now tooth colored), see Fig. 9.

As part of the next step, the restora-tions were reduced for individualization, in this case the incisal edge and the up-per third (Fig. 10 and 11).

VITA SUPRINITY offers excellent milling results both in its pre-crystallized state and following final crystallization. VITA VM 11 is processed in the same way as other VITA VM ceramics. Effect Enamel, Window and Enamel (light) materials were used here (Fig. 12 to 14).

Finally, glaze firing and polishing were carried out. The VITA SUPRINITY Polish-ing Set is particularly suited to simple polishing. Figures 15 and 16 show the completed restorations on the model.

ResultFigure 17 shows the final result follow-ing permanent bonding. With compara-tively little effort, the wishes and ex-pectations of the patient were implemented perfectly. The patient is very happy with the result.

A graduate in business administra-tion, Erich Daniel has been the new ex-port manager at VITA Zahnfabrik since June 1st, 2013. In this interview, he re-veals his origins, his goals, and what makes him unique as a person.

Mr. Daniel, tell us a little about yourself!

Born in 1962 in Caracas, Venezuela, childhood spent all over the world, Ger-man father, Spanish mother, married, two children, and a salesman with a pas-sion for sales.

As a youth, you had already lived in more countries than most people get to visit in their entire lifetime. How come?

My father was a brewmaster, and what is known as an expatriate, so he was sent by his employer to work in different foreign locations. We moved with the family every three to four years – Latin America, Europe, Africa.

That obviously has consequences – I‘m simply far too fond of being on the road and in this respect also at home in a way when I am abroad.

Which brings us to your “new” posi-tion at VITA: what are your duties in this role?

Dental technicians and dental surgeons in more than 150 countries now place their trust in materials, products and all-in-one solutions from Bad Säckingen.

Our sales activities are divided into three areas: Germany/Austria, the rest of Europe and – this is where I come in – all countries outside of Europe (with the exception of the USA). As export manager, I am responsible together with our small, dynamic export team for for-mulating and implementing our opera-tive and strategic goals.

What experience do you bring to this role?

I am a conventional business administra-tion graduate, specializing in marketing and foreign trade. I have been involved in international sales right from the start of my career, and so have unfortunately never had the opportunity to familiarize myself with the German market.

I lived and worked in Peru for four years and for over three years in Venezuela; and in China, I helped establish a subsid-iary for a German company. Having en-tered the chemical industry, I worked for several years in pharmaceuticals, and most recently spent a good ten years as the export manager at Lamy, a manufac-turer of writing instruments in Heidel-berg, Germany.

VITA INFO 2.13 10

How has your experience been of VITA so far?

VITA operates in a highly-dynamic sec-tor of the health care market and is an established, successful player. The strengths of a family-run company such as short chains of command, a strong image, reliability, and solidarity with one another are also evident. A good choice.

What do you enjoy most about your work?

No country in which VITA exports its products is like any other. Each one pre-sents a new challenge. You are never bored, that is the real attraction.

How do you spend your time when you aren‘t traveling the world for VITA?

My family is then obviously my priority, a large part of which lives in Spain by the way. I also love science fiction novels and enjoy country music as well as any music from the 1970s.

Thank you for talking to us, Mr. Daniel!

The China International Dental Exhibition & Scientific Conference is to Asia what the International Dental Show is to Europe. Known as Sino-dental for short, it is traditionally the trade show for dental technology and dentistry products that attracts the most visitors.

Sinodental 2013Sinodental has become the most impor-tant platform for the international dental industry in the Asian region. This year, 705 companies from 22 countries took part. As part of the trade fair from June 9th-12th, 2013, the German Federal Ministry of Economics and Technology (BMW-i) once again presented a “German Pavilion“. For the first time, this was ac-companied by an exhibition showcasing the German dental industry, aimed at drawing attention to the leading role that it plays in innovation and research. This year, Germany‘s share of overall partici-pation was around ten percent, with around a quarter of non-Chinese exhibi-tors coming from Germany. 40,000 visi-tors were registered.

Special German exhibitionSinodental was opened by Chen Xiao-hong, Deputy Minister at the time at the Chinese Ministry of Health (Fig. 1), and Stefan Kapferer, Secretary of State at the German Federal Ministry of Economics

and Technology (Fig. 2). Directly after-wards, the latter visited the special Ger-man exhibition “Innovation and Re-search“, which attracted a lot of interest. Here, the latest processes and products for dental laboratories and dental practic-es were presented live in a futuristically designed, hands-on “Science Lab“.

Stefan Kapferer was visibly impressed. According to the secretary of state, it is the fact that medium-sized businesses are ready to focus on markets abroad that makes the German economy so strong. The key factors in its success are its con-sistent strength of innovation and ulti-mately the outstanding quality of prod-ucts “Made in Germany“. Digitalization is setting the pace in dental technology, with computer technology supporting processes from scanning the jaw through to final restoration.

As a result of continuing improvements in production processes and materials, res-torations are becoming more long-lasting and more natural in appearance. One ex-ample in this respect is the hybrid ceram-ic VITA ENAMIC. The German politician learned more about this material during his tour of the trade show booth set up by VITA Zahnfabrik‘s Chinese sales partner TESCO DENTAL.

Market launch of VITA ENAMICAt Sinodental, the CAD/CAM restoration material VITA ENAMIC was officially launched on the Chinese market as part of a 3-hour event (Fig. 3 to 5). 300 laboratory and practice professionals who were in attendance were provided with further details as well as comprehensive back-ground information about the innovative material concept that combines the best of what ceramic and composite materials have to offer (Fig. 6). The feedback provid-ed by over a dozen dental technicians and dental surgeons from all over the world who had already gained experience at the time in using VITA ENAMIC (Fig. 7 and 8) met with particularly strong interest.

Sinodental will take place again in China from June 9th-12th, 2014 at the National Convention Center in Beijing.

POSITIVE RESPONSE TO HYBRID CERAMICS IN NORTH AMERICA

Following the successful launch of VITA ENAMIC on the German market, this hybrid ceramic has also won the hearts and won over the milling machines of American users.

Around 14,000 Sirona CEREC systems are installed in American practices – and this does not include the Sirona in Lab sys-tems in laboratories. Accordingly, there is considerable interest in innovative new developments in the area of CAD/CAM restoration materials. The hybrid ceramic VITA ENAMIC has enjoyed a fantastic start in the land of opportunity, with the experts in the CEREC Doctor community also among those who have been im-pressed. This includes Dr. Mark Fleming, for example, a member of the Mentor Group who is responsible for the CEREC Doctors information magazine.

The cover page of the first issue in 2013 shows Dr. Russel Giordano, who explains the VITA ENAMIC concept that he helped to develop in an interview included here

(Fig. 1). At www.cerecdoctors.com, the e-paper can be called up free of charge via the Magazine menu item.

Together with Prof. Werner Mörmann, the father of CAD/CAM technology, Dr. Robert Kelly from the University of Con-necticut, and Dr. John Carson from Tuc-son, Arizona, both professionals ex-plained the innovative material to their colleagues, also doing so at events such as the CEREC Doctors annual meeting in Scottsdale, Arizona (Fig. 2 and 3). To this end, a curriculum lasting half a day was presented, which comprised a live demonstration of a patient restoration using VITA ENAMIC – with a community member as the subject – and a podium discussion. For the participants, this was a unique opportunity to speak with not just one but several of the most important developers of CAD/CAM materials in the world. Prof. Mörmann in particular met with an enormous group of fans who cheered him almost like a rock star!

Active supportDental technicians and dental surgeons in more than 150 countries rely on materi-als, products and all-in-one solutions from Bad Säckingen. Thanks to an inter-national sales network that is built on customer proximity, reliable local con-tacts are available throughout the world. Our competent partner in North America is the VITA subsidiary Vident, headquar-tered in Brea, California. In order to en-sure that VITA users everywhere enjoy the same superior customer care, we collaborate very closely with all sales partners.

Fig. 3: Participants at the CEREC Mentors Group meeting in Scottsdale, Arizona, USA.

For this reason, a Vident team comprised of staff members from application sup-port, marketing, technical support and continuing education traveled to Bad Säckingen in January 2013. During their visit they were thoroughly familiarized with all VITA ENAMIC technical specifi-cations and were provided with hands-on training that included staining and glazing of restorations, for example (Fig. 4).

Presentation at the Chicago Midwinter MeetingAs a result, it was possible as early as February 2013 to announce the launch of VITA ENAMIC during the Chicago Dental Society (CDS) Midwinter Meeting (Fig. 5). This year was the first time that Vident had an exhibition stand of this size, with the VITA ENAMIC displays providing the main attraction. They were identical to those used at the VITA exhibition stand at the International Dental Show (IDS) in March 2013 in Cologne, Germany.

Other highlights included the “Shade ID“ station, where shade measurements, for example, were performed using VITA Easyshade Advance 4.0. Participating vis-itors to the stand received a personalized badge with their photo and the result of the measurement as a souvenir. Vident expects that in the same way as the inno-vative hybrid ceramic VITA ENAMIC, the new glass ceramic VITA SUPRINITY will also be very well-received by users when it is launched in North America.

… that is the motto of the VITA courses for dental surgeons and den-tal technicians (Fig. 1). A team of out-standing speakers who understand what really matters ensure that these expectations are reliably met.

At the central locations of the VITA Academy in Langen near Frankfurt am Main and Bad Säckingen, a varied and challenging program of events is of-fered. Examples include practical train-ing programs and courses, as well as after-business events and other events. At the same time, regional courses and workshops are held at 25 locations in Germany and Austria. In addition, it is also possible to hold training events di-rectly in laboratories or dental practices.

A highly qualified team of speakers en-sures application-based training that is tailored to the individual participant structure by didactically adapting it to suit the knowledge and abilities of the individual participants. All interested parties will have the opportunity to get to know the VITA course instructors more closely.

Beginning with this issue of VITA Info, they will be introduced in a series of articles, one after another and in alphabetical order. A short biography of each speaker is also available online at www.vita-zahnfabrik.com in the Educa-tion section.

Axel Appel, master dental technicianThe master dental technician Axel Appel was employed from 1989 to 2001 as a dental technician and manager in a com-mercial laboratory. In 2001 he success-fully passed the exams to become a master dental technician, and was then employed first in the Bonacina & Ve-

dovelli dental laboratory in Bergamo, It-aly, then in the practice laboratory of Dr. Leitzbach in Hochheim/Main, Germa-ny. Since July 2004, he has been work-ing as an application consultant for VITA Zahnfabrik.

Axel Appel, master dental technician: “I manage the events that are part of the official course program and support in-terested parties and users directly ons-ite on their premises. Should new ques-tions arise following the introduction of VITA materials or if any kind of trouble-shooting is required, I am happy to help or advise – long-term customer care is very important to me. The individual needs of each customer are paramount, both during a course and when it comes to onsite application support.

A clear trend can be observed towards CAD/CAM. The corresponding training events, particularly for VITA ENAMIC and VITA SUPRINITY, are very much in demand.

The topic of ceramics and composites is also always very popular. By directly com-paring a zirconia crown veneered using VITA VM 9, a metal crown with VITA VM 13 layering and a metal crown individual-ized using VITA VM LC, for example, I par-ticularly enjoy demonstrating how just consistent the results are that can be achieved using the VITA VM concept.“

Gerwin Arnetzl, university professor.

Prof. Gerwin Arnetzl is a dental surgeon specializing in oral and maxillofacial sur-gery, as well as an expert in the adhe-sive and all-ceramic techniques. He has been head of the working group on re-storative dentistry and adhesive pros-thetics at the Clinical Department for Prosthetic Dentistry of the University of Graz, Austria since 1995.

Since 2000, he has been President of the Austrian Society of Computerized Den-tistry, and since 2007, Vice President of the International Society of Computer-ized Dentistry.

He has published over 110 scientific arti-cles and held more than 250 lectures at

home and abroad. His reference books on all-ceramics have been translated into six languages.

Of particular benefit in his teaching role and in his engagements as a speaker is the fact that he not only has a scientific background, but that he continues to practice at his surgery “Ordination am Kai“. This ensures that he does not lose touch with everyday practice.

Gerwin Arnetzl, university professor: “In my opinion, the ideal course should be

both informative and entertaining. For VITA, I generally hold seminars on all-ce-ramics that focus on design appropriate to the use of ceramics. This is both an important and fascinating topic as the preparation is the basis for every resto-ration and is entirely in the hands of the dental surgeon. My goal is to provide course participants with a compact overview of how all-ceramic restora-tions work, as well as to demonstrate in a simple, transparent fashion how mis-takes can be avoided.“

Rosita Bacher, dental technicianIn 2012 the dental technician Rosita Bacher celebrated her 25th year at VITA Zahnfabrik. Since July 1st, 1987, she has been employed both in sales and as a speaker. She has been a course instruc-

tor since 2011 for the southern region and Austria as well as manager of the VITA CAD/CAM training center in Schwaig, Germany.

On her days off, she likes to spend time in her home away from home on the Spanish island of Gran Canaria. This has developed into projects such as the workshop “Gran Dentissmo on the Ca-

Rosita Bacher, dental technician: “I fully support the products as well as our cor-porate philosophy. I really enjoy my role as course instructor. For me, it is impor-tant to take care of customers on an indi-vidual basis and to train them according to their needs. I have guided many of our loyal customers who now operate their own master laboratory since their days as trainees – long-standing collaborations of this kind establish a strong bond.“

New: The hybrid ceramic VITA ENAMIC can be processed using Ceramill Motion 2 from AmannGirrbach as well as the CAD/CAM systems from KaVo dental (Fig. 1 to 4).

There are currently 57,651 dentists in practice in Germany. Using CAD/CAM systems for chairside applications, they can process ceramic blanks that have been pre-colored in accordance with the tooth shade directly in their practice. However, it is a fact that firstly, not all indications can be treated using the chairside approach, and secondly, only approx. 7,000 dental practices are equipped with a milling unit. Any of the 50,000 other dental surgeons who wish to use all-ceramic prostheses must rely on the services of a dental laboratory.

Targeted collaborationsThe Ceramill Motion 2, KaVo Everest and KaVo ARCTICA CAD/CAM systems are tried-and-tested in laboratory use. With these systems, the dental technician can avail of validated process chains, mean-ing that the software and hardware as

well as the tools and materials are tai-lored to one another. As a result of its pi-oneering achievements in CAD/CAM technology, VITA Zahnfabrik is in consid-erable demand as a competent material supplier and supports corresponding col-laborations with selected partner compa-nies. After all, targeted collaborations provide the ideal foundation for flexible, simple and reliable use of VITA CAD/CAM materials.

New material optionIt has already been possible for some time now to use VITABLOCS Mark II and TriLuxe forte with Ceramill Motion 2. The KaVo Everest engine and ARCTICA en-gine also enable processing of VI-TABLOCS RealLife and VITA CAD-Temp. And now since September 2013, VITA ENAMIC is also available for all three ma-chines. This dental composite material is suitable for all conventional single-tooth restorations such as inlays, onlays, ve-neers and crowns, for restorations sub-ject to high occlusal load (molar area) in particular, as well as for minimally-inva-sive restorations. VITA ENAMIC is availa-ble in HT (HT = Highly Translucent) and T

(T = Translucent) translucencies, as well as in the following five VITA SYSTEM 3D-MASTER shades in each case: 0M1, 1M1, 1M2, 2M2 and 3M2. The restora-tions can be polished using VITA ENAMIC Polishing Sets or characterized using the VITA ENAMIC STAINS KIT.

AnnouncementBy the middle of next year, the zirco-nia-reinforced lithium silicate ceramic (ZLS) VITA SUPRINITY will not only be available for the CEREC/inLab system from Sirona, but will also support pro-cessing using KaVo Everest and ARCTICA machines as well as using Ceramill Mo-tion 2 from AmannGirrbach.

VALIDATED LABORATORY PROCESSES FOR VITA CAD/CAM MATERIALS

There are increasingly fewer dental technicians, and they are required to fab-ricate restorations of increasingly superi-or quality within an increasingly short time frame. Working under significant pressure requires efficient production techniques that deliver reliably reproduci-ble results. This is also true of veneers.

A veneering system must meet a number of requirements in order to reflect current technological standards: excellent es-thetics and perfect surfaces are required.

Simple handling and a reliably reproduci-ble shade concept are also required – re-gardless of the type of restoration select-ed, or whether all-ceramic, metal ceramic or acrylic material is used. Dental tech-nology instructor Vanik Kaufmann-Ji-noian of Cera-Tech, based in Liestal, Switzerland (Fig. 1) has chosen a veneer-ing system that meets all of these re-quirements: VITA VM.

A uniform approach for all VITA VM mate-rials allows him to use standardized pro-cesses as well as enabling accurate shade reproduction.

At the Cera-Tech dental laboratory, 20% of the restorations fabricated are com-prised of metal ceramics. All-ceramic solutions make up 80% and include zirco-nia restorations, for example, as well as those comprising feldspar ceramics such

as VITA Mark II. The tools used here to process these framework materials in-clude the inLab MC XL milling machine from Sirona (Fig. 2). For individualization of veneers, VITA VM 9 (Fig. 3) and VITA VM 13 are used.

I do it my way!Each patient is unique, as are their resto-rations, but one thing always remains the same: dental technology instructor Vanik Kaufmann-Jinoian has developed his own personal approach that creates a reliable basis for every veneer – regardless of the indication or framework material, etc. His approach to layering is similar to that of composite materials, in which the shape of the tooth is fully layered immediately. Starting at the center, a large quantity of Base Dentine is applied, followed by enamel. According to dental technology instructor Vanik Kaufmann-Jinoian, layer-ing in this way using VITA VM BASIC is

perfectly sufficient in order to achieve positive results (Fig. 4) when individualiz-ing crowns and bridges for the posterior area. He modifies the approach for anteri-or restorations by also applying smaller quantities of Transpa Dentine in order to enhance the effect of depth. To perform firing, VITA VACUMAT 6000 M is used in accordance with the instructions of the manufacturer.

Dental technology instructor Vanik Kauf-mann-Jinoian: “A significant benefit of VITA VM materials is superior handling. Unlike competitor materials, they remain moist for longer so that even large-span restorations can be layered without dry-ing out.“ He requires six minutes just to perform layering; the high strength of the materials in particular is an important prerequisite for fast layering of this kind(Fig. 5). This Swiss dental professional summarizes his approach to layering as follows: “Speed and moisture mean bet-ter esthetics!“

Glaze is also applied to each restoration on completion. The handy new VITA AKZ-ENT Plus GLAZE SPRAY is used for this purpose (Fig. 6) – and this is not the only reason why dental technology instructor Vanik Kaufmann-Jinoian is a fan of the spray technique.

At the touch of a button!This dental technician believes in effi-ciency and swears by the VITA SPRAY ON system (Fig. 7a). That‘s because this inno-vative tool offers fast, homogeneous and wafer-thin application of opaquer materi-als, for example (Fig. 7b), all at the touch of a button. Initial mixing of material for the spray technique should be performed using an ultrasonic unit in order to ensure effective mixing.

In the case of VITA VM 9, WASHBAKE firing is recommended as the first step in order to achieve a secure bond between the zirconia and the VITA VM 9 material. Application at Cera-Tech is also carried out using the VITA SPRAY ON system. It can be performed using either BASE DENTINE, CHROMA PLUS or EFFECT LINER materials. It is also possible to spray on CHROMA PLUS material in the neck area in order to achieve a more in-tensive shade effect with VITA classical A1–D4 shades.

Tip: Artificial fingernails make outstand-ing templates for this purpose.

ConclusionThe VITA VM veneering concept not only provides the right solution for any indi-cation, it also creates the ideal basis for allowing all dental technicians to relia-bly achieve their goal quickly and easily using their preferred approach.

By offering custom biocompatible prostheses, practices and laborato-ries can reach new potential custom-ers in the areas of holistic dentistry and dental technology.

Specialist networkDental surgeons are required to place ex-ogenous materials in the bodies of their patients on a permanent basis. Every ma-terial can, however, be the trigger for chronic inflammation. At the same time, dentists are increasingly dealing with pa-tients who are already suffering from in-flammatory conditions. In such cases, the non-biocompatible materials and sources of irritation must be specifically identified in order to prevent further inflammatory stimuli that could have a negative impact on the existing condition.

Intolerances are determined by conduct-ing medical laboratory tests on the patient using heparin blood testing and/or bioen-ergetic analysis. Individual substances as well as entire composite materials are

tested with regard to sensitizing, inflam-matory or allergic responses. Non-bio-compatible substances, for example, in prostheses must be excluded. This re-quires detailed knowledge on the part of the dental technician with regard to mate-rials and their constituents.

Successfully providing patients who are predisposed to these difficulties with res-torations can be achieved through net-working between dental surgeons and specialists such as the master dental technician Petra Junk (Fig. 1) who oper-ates the Ceradent dental laboratory. This professional laboratory is certified in ho-listic dental technology by the GZM and the DGUZ, two German professional asso-ciations for holistic dental medicine.

She has spent almost 20 years focusing on the issue of biocompatibility in dental prosthetics and describes her recipe for success as follows: “In close collaboration with a dental surgeon who favors a holis-tic approach, we fabricate biocompatible prostheses, the composite materials of which are tailored specifically according to each particular individual patient and their diagnosis. Thanks to our specializa-tion as well as the particular care that we take in our work – from the selection of the materials through to the procedures used during processing – we are a quali-fied and reliable partner.“

Only the appropriate processing using op-timized processing techniques ensures that a material that is normally biocompat-ible does not result in further exposure of the patient due to the production/release of harmful substances. This includes mod-ern metal processing techniques, as well as firing based on a holistic concept when veneering zirconia frameworks, and the processing of high-performance polymers.

Risk detected, risk eliminated!Before the master dental technician Petra Junk adds a material to her portfolio, she subjects it to comprehensive investigation and application testing. She has a particu-larly watchful eye when new “multi-func-tional“ materials come onto the market. In her experience, a broad range of indica-tions is usually achieved by adding syn-thetic materials that demonstrate the greatest potential for risk.

The goal of holistic dental technology is to limit the use of exogenous materials as far as possible, to test these in advance in terms of their biocompatibility, and to pro-cess them in accordance with their indi-vidual susceptibility.

It is important for the dental technician to be able to rely on the manufacturer to pro-vide a consistently high level of material quality that is tested on an ongoing basis.

In the experience of the master dental technician Petra Junk, the materials sup-plied by VITA Zahnfabrik are more suitable than competitor products for patients who are predisposed to these difficulties. Ex-amples of this include:

• The veneering ceramic VITA VM 9 (Fig. 2 and 3) is comprised exclusively of na- tural materials and does not contain any synthetic additives

• VITA acrylic teeth (Fig. 3 to 5) do not contain methyl methacrylate (MMA)

• The VITA CAD-Temp composite blanks do not contain MMA either and facilitate particularly hypoallergenic long-term tem-poraries

VITA Zahnfabrik was founded on July 17th, 1924, and has since con-sistently advanced the cause of dentistry …

What began in 1924 as the vision of one man has developed in the meantime into one of the leading companies internation-ally in the dental industry. For genera-tions, VITA Zahnfabrik has stood for pio-neering innovation and continued progress. As a family-run company with a long history, we also guarantee dependa-bility and reliability.

Our focus at VITA has always been on the needs and requirements of dental techni-cians, dental surgeons and patients – and to meet these needs only with products that offer quality above and beyond any conventional standards. With this in

mind, the best raw materials, technical expertise and innovative production pro-cedures combined with permanent con-tact with the user provide the basis for the VITA product and service portfolio.

Looking backThe upcoming 90th anniversary is a good opportunity to pause and reflect. One of the earliest major milestones in the com-pany history was the development of the first VITA dental ceramic for the fabrica-tion of custom dentures in 1930. And since 2003, dental technicians around the world have been benefiting from the uni-form VITA VM concept for ceramics and acrylics. The vacuum-fired ceramic teeth VITA LUMIN VACUUM were introduced in 1956.

Since 2001, the dental world has benefit-ed from acrylic teeth with convincingly natural characteristics in the shape of VITA PHYSIODENS. Even today, the VITA-PAN classical A1–D4 shade system intro-duced in 1983 remains an international benchmark. It was joined in 1998 by the VITA SYSTEM 3D-MASTER system – and since 2008, the VITA Linearguide 3D-MASTER and VITA Easyshade Com-pact have been making precise determi-nation of the correct tooth shade even easier.

Yet another highlight is the premium ce-ramic furnace VITA VACUMAT 6000 M, which was launched for the first time in 2009 together with the VITA vPad control unit that is available in three different models. VITA has also always been a pio-neer in CAD/CAM technology. The intro-duction of VITA InCeram YZ pre-sintered zirconia blanks for the fabrication of all-ceramic crowns and bridges in 2002 as well as the launch of VITABLOCS Real-Life with its three-dimensional block structure comprising a dentin core and

enamel shell in 2010 are just some exam-ples. More recently, VITA has once again lived up to its reputation as a trend setter with the development of the hybrid ce-ramic VITA ENAMIC and the new glass ceramic VITA SUPRINITY.

Going forwardWhile a lot has changed in the last 90 years in the world of dentistry, one thing remains the same – the reliability of VITA Zahnfabrik. And dental technicians and dental surgeons throughout the world can continue to rely on us. We may not be able to predict the future but we can play a crucial role in shaping it!
